Today I was working in an unheated building. It was a "round house". House
set up by the beach, along the edge of a lake. Designed as a summer home for
the waterfront director of a camp.

Masonry structure, cinder block wall. Probably 20 foot diameter, about 9
foot ceiling. It was 37F outdoors, and there was a thermometer indoors, said
it was 40F.

I lit up a one burner camp stove, Coleman $20 unit from Walmart. I could
barely feel any difference, in the indoor temp. probably 4,000 or 5,000 bTU.
After a while, the tank got frosty, and the flame went down. I heated the
tank with a propane torch, and the flame went back up for a few minutes.

After a while, the camp got us a "milk house" heater, and we plugged that
in. 1500 watts. Which helped a little. By the time I left, it was 50F
indoors.

What I'd like, some kind of "weed burner" to burn a lot of propane in a
hurry. Raise the temp from 40 to 60 would be really nice.

It should work on a 16 ounce propane bottle. It's OK to invert the bottle,
to feed liquid propane to the burner. Small enough to carry in the van with
the rest of my tools. Should be relatively safe, if supervised by an adult.
Doesn't necessarily have to be OSHA approved. It's just for occasional use.
Any ideas? Weed burner, maybe?

Most BTUs/hr per buck is a Cajun Cooker type unit. Most BTUs/hr absolute
at reasonable cost is a propane-fired salamander.

Unvented indoor heating with propane for any length of time will build up
some pretty noxious fumes very quickly. Even if the CO2 and CO don't get
you, the NOx's build up and irritate your respiratory system like the worst
possible smog-polluted cityscape. Ventilating enough to keep those
concentrations down will defeat the heating.

Wear lots of warm clothes or wait until May.

Not gonna work for you. You want more BTUs than one of those bottles
can produce without freezing up. Get a little heater that uses BBQ
style tanks.

Mr. Heater makes a 9000 BTU one that works off 1lb tanks- or a hose to
the BBQ tanks. [on sale on Amazon -northern Tool- for $60 - search
#mh9b]

I think at 40 degrees the 1lb tank would be more trouble than it's
worth. At about 20 you'd probably want to sit the 20 in a tub of hot
water.

I'd spend $80- and get the 55000 btu - free shipping through Amazon -
search #MH55FAV.

Does that adult heat propane cylinders with a torch? If yes- then
none of them are safe.<g>

OSHA is a PITA. But it has probably saved a lot of lives in the past
40 some years. [some would argue that they interfere with Darwin's
laws]

No you never invert propane bottles, you should know that, and heating
a propane tank with propane flame is not advised. 16oz wont do much
and as you saw froze. Get a 20 lb and a torpedo heater or a nice 2
burner infrared, the infrared will heat you immediatly and not the
air , direct it at your direction even from 20 ft away and you will be
warm even at 0f
